SPECIFICATION forming part of Letters Patent No. 498,637, dated May 30,1893.

I Application filed August 30, 1892. Serial No. 444,529. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES C. EMMONS,

I of Pittsburg, in the county of Allegheny and State of Pennsylvania,have invented certain new and useful Improvements in Plaiting-Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and it, reference being had to theaccompanying drawings, which form part of this specification.

My invention relates to improvements in plaiting machines; and itconsists in the conby the plaiter blades when making a number.

of box plaits, and to automatically move out of the way when the goodsare fed forward to the stitching mechanism.

Another object of my invention, is to provide inwardly extending fingerswhich are under the goods being operated upon, and near enough to theholding device to form abreak or bend in the goods at this point,whereby the plaiter blades are materially assisted in forming a perfectplait.

In theaccompanying drawings :-Figure 1 is a perspective view of myinvention complete, showing it in connection with a plaiting mechanism.Fig. 2 is a cross section of my invention showing it in a holdingposition. Fig. 3 is a similar view showing the holding device in areleased position to allow the goods to move to the stitching mechanism.Fig. 4: is a detached view of a laterally adjustable yoke to which asupporting connection of the holding device is fastened. Fig. 5 is adetached plan View of the fingers and a portion of their supporting rod.

My present invention is intended to be applied to and operated inconnection witha plaiting machine fully shown and described in PatentNo. 422,215, dated February 25, 1890. In Fig. 1 the right hand plaitingmechanism shown in said patent is illustrated, as also the stitchingmechanism therefor, the left hand presser foot, and the left handplaiter blades,

but the mechanism for operating the latteris omitted.

A is the shaft carrying thecams B for operatin g the right hand plaiterblades, and this same shaft also carries .cams, as shown in the'clamping screw 6 passes into the arm or beam I of the machine, wherebythe said yoke .is capable of longitudinal adjustment thereon for apurpose to be fully described farther on. 'Secu'red at one endtof theyoke D is a depressing spring H, which has its opposite end secured tothe inner end of an arm G, the outer end of said arm being in the pathtraveled by a cam J, secured to the shaft A, and by means of which thesaid arm is raised at its outer end, and allowed to be depressed when itcomes to a cut away portion of the cam, as will be readily understood.

The holding device L is attached to the lower end of a rod K, the upperend of said rod being suitably connected with the arm G. In order tohold the rod K to which the holder is attached, and prevent it fromhaving any movement other than a' vertical one, a brace rod M has oneend provided with an opening through which the rod K passes, and itsopposite end extending into a socket N at the lower end of the yoke, andclamped by means of a set screw P. As shown, the. upper end of the rod Kis preferably pivotally connect-- ed with the arm G, whereby thelowerend of the rod K can be adjusted in and out by means of the adjustablebrace rod M, for a purpose to be fully described presently.

The operation of this holding device is as follows:The cam J is placedin such relation to the cams B for moving the plaiter blades, that theholder is allowed to be depressed upon the goods by its spring II whenthe plaiter blades are moving forward toward the stitching mechanism,whereby it holds the goods and assists in forming a perfect pufi, as

the plaits are being formed. After the plait is f0rmed,theholdingdeviceis raised byits cam, and the plaits formed are then sewed by themachine. For the purpose of still further assistingthe plaiter blades informing a perfect plait, I provide inwardly extending fingers R whichare connected at their outer ends to a supporting rod Q and clampedthereto by means ofa screw I). These fingers are made extensible bymeans of pieces S placed under them, which are held by set screws whichpass through slots a, made in either the extension S or the finger R asmay be found expedient. The fingers are capable of vertical movement attheir inner ends by being turned upon their supporting rod and clamped,and are made adjustable lengthwise by means of the movable pieces S.These fingers are placed under the goods as illustrated in Fig. 1 bydotted lines, and have their inner ends sufficiently near the holdingdevice whenit is depressed, to form a break or bend in the goods at theproper point for a plait, whereby the formation of the plait in properform by the blades is facilitated. These fingers are also adjustableupon the supporting rod Q, whereby they can be brought nearer together,or separated, according to the distance between the two plaitingmechanisms, as provided for in the said patent. So also owing to'theconstruction of the yoke, the holding device is capable of adjustmentacross the goods forthe same purpose.

From the above description, it will be seen,

that the holding device is capable of two adjustments, one lengthwisethe goods, and one across the goods, which enables it to be placed atany desired point to best carry out the purpose for which it isintended. The adjustment sidewise is to adapt it to different widths ofgoods being plaited, and the adjustment back and forth or in aline withthe of the plait being made.

length of the goods is to adapt it to the width The adjustment of thefingers sidewise upon the rods is to adapt them to any desired width ofgoods, and the adjustment endwise is to adapt them to the desired widthof plait, and the adjustment vertically is to give a. deep orshallowbend to the goods when engaged by the holding device. Q g

It will be understood that the end of the rod K could be made to servethe purpose without any holding device L'connected thereto.' I alsodesire it understood that I do not limit myself to any particular meansfor moving the holding device, for this may be varied at will withoutdeparting from the spirit of my invention, which is to provide anautomatically acting holding device, which holds the goods while a plaitis being formed, and then releases them to be fed to the stitchingmechanism.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination with the arm of a sewing machine, of a plaitingmechanism comprising plaiting blades, a shaft elevated above the bed ofthe machine and at one side of the said arm, a cam carried by saidshaft, a vertically moving arm extending transverse the said shaft andsewing machine arm, one end of the vertically moving arm supported bythe sewing machine arm and its opposite end engaging said cam,andaholding and releasing rod operated by the said transverse arm the partsoperated for the purpose described.

2. The combination with a plaiting mechanism, of a vertically movingarm, a camfor moving it, a support for said arm, a holding and releasingrod, loosely connected at its upper end to said vertically moving arm,and a brace rod for the lower end of said holding and releasing rod.-

3. The combination with a plaiting-mechanism, of an arm, a supporttherefor, a cam for moving the arm vertically, a holding and releasingrod loosely connected at its upper end to said arm, and an adjustablebrace rod for the lower portion of said holding and releasing rod.

4. The combination with a plaiting mechanism, of a transverselyadjustable yoke, a support therefor a vertically moving holding andreleasing rod connected with the yoke at its upper end, a cam for movingthe rod vertically and a brace rod for the lower end of said holding andreleasing rod.

5. The combination of a plaiting mechanism, of a yoke, a supporttherefor a vertically moving holding and releasing rod connected at itsupper end with the yoke, a cam for moving the rod vertically, and abrace rod having one end connected with the said yoke and its oppositeend supporting the lower portion of the holding and releasing rod.

(5. The combination with a plaiting mechanism including plaiter blades,of a vertically moving holding and releasing device, a

ing an adjustment longitudinal the movement of the plaiter blades. I

7. The combination with a plaiting mechanism, of a rod, an extensiblegoods support laterally adjustable upon said rod, and a verticallymoving holding rod adjacent to the inner end of said support.

8. The combination with two plaitingmechanisms, and two stitchingmechanisms of a holding and releasing device for the goods beingoperated upon, the said device being situated between the blades of thetwo plaiting mechanisms, and between their inner ends and the stitchingmechanisms.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES C. EMMONS.
